Garlic and cholesterol--Does everyone now need Lipitor?

Garlic May Not Lower Cholesterol
Study Shows No Improvement in Cholesterol Levels From Raw Garlic or Garlic Supplements

Lots of reports continue to hit the press about a small study that hoped to determine whether garlic as whole cloves (4 to 6), an aqueous extract of garlic called Kyolic, or an oil extract called Garlicin (high in allicin), or placebo. No differences in lipid numbers including LDL cholesterol were observed.

I believe that the researchers were sincere in their effort to follow an honest, scientfically sound clinical trial design. I'm personally not that surprised. The effect in prior studies has been modest, sometimes none. Does that mean that we should ignore the other studies that suggest there may be modest blood-thinning, anti-inflammatory, blood pressure-reducing, and cancer-preventing properties? No, it does not. Dr. Matt Budoff at UCLA even published a very small study in about 20 people that suggested a slowing of plaque growth by using Kyolic in persons tracked by CT heart scans.

Nonetheless, garlic is, at best, probably no more than a source of small benefits. The biggest fallout from this kind of report, however, is not the neutral results from garlic, but from the open door the drug companies sense when this happens.

If you read the WebMD report, you'll notice all sorts of advertisements from drug companies for statin cholesterol drugs ("Cholesterol health center"; "Understanding Cholesterol Numbers"; "There are two sources of cholesterol: food and family"), Niaspan (which I used to support but have been discouraged by the Kos companies excessively profiteering methods and recent big Wall Street sellout).

It doesn't follow. The failure of one nutritional strategy to reduce LDL does nothave to trigger a run to the drugs. Don't fall for it. Drugs have their place. So do supplements and food choices, which can be very powerful. Drug manufacturers and their marketing people salivate when something like this comes along, an open invitation to say, "If garlic doesn't work, _____ sure does."

Carbohydrate sins of the past

Carbohydrate sins of the past

Fifty years ago, diabetes was a relatively uncommon disease. Today, the latest estimates are that 50% of Americans are now diabetic or pre-diabetic.

There are some obvious explanations: excess weight, inactivity, the proliferation of fructose in our diets. It is also my firm belief that the diets advocated by official agencies, like the USDA, the American Heart Association, the American Dietetic Association, and the American Diabetes Association, have also contributed with their advice to eat more “healthy whole grains.”

When I was a kid, I ate Lucky Charms® or Cocoa Puffs® for breakfast, carried Hoho’s® and Scooter Pies® in my lunchbox, along with a peanut butter sandwich on white bread. We ate TV dinners, biscuits, instant mashed potatoes for dinner. Back then, it was a matter of novelty, convenience, and, yes, taste.

What did we do to our pancreases eating such insulin-stimulating foods through childhood, teenage years, and into early adulthood? Did our eating habits as children and young adults create diabetes many years later? Could sugary breakfast cereals, snacks, and candy in virtually unlimited quantities have impaired our pancreas’ ability to produce insulin, leading to pre-diabetes and diabetes many years later?

A phenomenon called glucose toxicity underlies the development of diabetes and pre-diabetes. Glucose toxicity refers to the damaging effect that high blood sugars (glucose) have on the delicate beta cells of the pancreas, the cells that produce insulin. This damage isirreversible: once it occurs, it cannot be undone, and the beta cells stop producing insulin and die. The destructive effect of high glucose levels on pancreatic beta cells likely occurs through oxidative damage, with injury from toxic oxidative compounds like superoxide anion and peroxide. The pancreas is uniquely ill-equipped to resist oxidative injury, lacking little more than rudimentary anti-oxidative protection mechanisms.

Glucose toxicity that occurs over many years eventually leaves you with a pancreas that retains only 50% or less of its original insulin producing capacity. That’s when diabetes develops, when impaired pancreatic insulin production can no longer keep up with the demands put on it.

(Interesting but unanswered question: If oxidative injury leads to beta cell dysfunction and destruction, can antioxidants prevent such injury? Studies in cell preparations and animals suggest that anti-oxidative agents, such as astaxanthin and acetylcysteine, may block beta cell oxidative injury. However, no human studies have yet been performed. This may prove to be a fascinating area for future.)

Now that 50% of American have diabetes or pre-diabetes, how much should we blame on eating habits when we were younger? I would wager that eating habits of youth play a large part in determining potential for diabetes or pre-diabetes as an adult.

The lesson: Don’t allow children to repeat our mistakes. Letting them indulge in a lifestyle of soft drinks, candy, pretzels, and other processed junk carbohydrates has the potential to cause diabetes 20 or 30 years later, shortening their life by 10 years. Kids are not impervious to the effects of high sugar, including the cumulative damaging effects of glucose toxicity.

    The government advice to "eat more healthy whole grains" is not off-base.  But that's not what Americans did.  Instead they ate more fructose and replaced saturated fats with more polyunsaturated fats.  This is totally fundamentally different than eating a low-fat, high-carbohydrate diet like that of the rural Zulu tribe studied by T.L. Cleave or the Africans studied by Denis Burkitt and Hugh Trowell that were diabetes and obesity-free.  

    Americans are still not even coming close to the grain consumption of a century ago, when such diseases were exceedingly rare.

    At this link you'll find the slides of a short presentation on
    The Influence of high vs. low sugar cereal on children's breakfast consumption.
    There are some surprising findings.

    I found it at Cerealfacts.org website

    The situation in the UK is much the same. The breakfast cereals most likely to find at discounted prices are those with the most sugar.

    It's  often the case the choice of cereal going into the trolley is made by the child rather than the parent. There should be more restrictions on the promotion of pre-sweetened cereals to kids.

    In my early 60s I notice that I don't get much "kick" out of sugary foods as I might have earlier.  I've gotten to the point where I can't believe the amount of sugar in say cookies or ice cream...which I no longer buy.  

    I do now take several phyto-extracts...pomegranate...blueberry...cocoa...resveratrol...green tea...grape seed...etc.

    Pomegranate at least has been shown to moderate insulin response and maybe reverse atherosclerosis.

    Interesting, but this leaves out neogenesis within the pancreas. Assuming that glucose intake is reduced, wouldn't new beta cells be undamaged and have full functionality? [Unless progenitor cells are also damaged...]

    Wouldn't this be more along the lines of adult onset type 1 diabetes (insulin dependent)?  It seems like that is growing too but the real swell seems to be in Type 2 diabetes where you produce copious amounts of insulin but your tissues are resistant to it.

    That explains why my obese elderly mom has normal blood sugars even though she has always eaten diet high in simple carbs.

    Dr. A, your previous diet was indeed low fat and starch based but there was not much actual, real food in it!  I am missing the connection both here on this thread and in your blog, between people eating manufactured, food like substances that don't have much fat in them and are loaded w/ refined/highly processed starch carbs w/ almost zero fiber or nutrients in them, and the eating of actual whole grains, either fully intact or minimally processed.

    "Wouldn't this be more along the lines of adult onset type 1 diabetes (insulin dependent)? It seems like that is growing too but the real swell seems to be in Type 2 diabetes where you produce copious amounts of insulin but your tissues are resistant to it."

    If you haven't already, check out Jenny Ruhr's blog, Diabetes Update, and her related website, Diabetes 101.  Type II is being subdivided according to short and long-term beta cell function and insulin resistance.  Different genes cause different impairments.  Emerging is MODY (mature onset diabetes of the young), or type 1.5.  A defining characteristic is that the ability of the pancreas to secrete insulin declines slowly over time, rather than suddenly as in type I, but it declines no matter what the treatment.

    I am a Ketosis Prone Type 2 diabetic and it isn't necessarily true that glucose toxicity leads to permanent loss of pancreas functioning.

    Typically, we will lose all pancreas secretion and will go DKA, at that point we are essentially type 1's. We need insulin to survive but after 2 to twelve weeks of normal blood sugars we can be taken off insulin and we will have near normal blood sugars.

    Weird, yes, but there are thousands of us out there so this isn't uncommon.

    We seem to be severely intolerant of carbs so I too wonder what would have been the case, if years ago the carbs were taken out of my diet.

    Sadly, this is what happened to me. I had glucose problems by age 15, but they told me for years I was fine. There was less information available in those days. I stopped all soda and junk, but it was too late, my fate was sealed. My pancreas and teeth were damaged. Somehow I managed to eat fruit without getting headaches years later, so I thought fruit in moderation was healthy. I though my fatigue was from my mercury fillings, but now I realize some of my fatigue was from fruit sugar. I blame society and my parents, although I forgive my parents. I was fed tons of soda and every type of high glycemic junk food you can imagine.

Coronary disease is drying up!

Coronary disease is drying up!

I had an interesting conversation with a device representative this morning. He was a sales representative for a major medical manufacturer of stents, defibrillators, and other such devices for heart disease.

Since I'm still involved with hospital heart care and cardiac catheterization laboratories, this representative asked me if I was interested in getting involved with some of the new cardiac devices making it to market over the next year or two. "The coronary market is drying up, what with coated stents and such. We've got to find new profit sources."

Well, doesn't that sum it up? If you haven't already had this epiphany, here it is:

HEART DISEASE IS A PROFITABLE BUSINESS!

Why else can hospitals afford billboards, $10 million dollar annual ad campaigns, etc.? They do it for PROFIT. Likewise, device and drug manufacturers see the tremendous profit in heart disease.

The representative's comments about the market "drying up" simply means that the use of coated stents has cut back on the need for repeat procedures. It does NOT mean that coronary disease is on the way out. On the contrary, for the people and institutions who stand to profit from heart care, there's lots of opportunity.

Track Your Plaque is trying to battle this trend. Heart disease should NOT be profitable. For the vast majority of us, it is a preventable process, much like house fires and dental cavities.

Thank you, Crestor

Thank you, Crestor

I'm sure everyone by now has seen the Crestor ads run by drugmaker, AstraZeneca. TV ads, magazine ads, and the Crestor website all echoing the same message:

"While I was busy building my life, something else was busy building in my arteries: dangerous plaque."

While previous drug trials with Mevacor, Pravachol, Zocor, and Lipitor have focused mostly on examining whether the drugs reduced incidence of cardiovascular events, Crestor studies have also focused on effects on atherosclerotic plaque volume. The best example is the ASTEROID trial that demonstrated approximately 7% reduction in plaque volume by intracoronary ultrasound.

So the AstraZeneca decision makers took the leap from cholesterol reduction to plaque reduction.

I'm sure this switch wasn't taken lightly, but was the topic of discussion at many meetings before the decision to make plaque reduction the focus of hundreds of millions of dollars of advertising. After all, billions of dollars are at stake in this bloated statin market.

Ordinarily, I couldn't care less about how the drug manufacturers conduct their advertising campaigns. But this one I paid attention to because the Crestor ads are helping fuel a new way of thinking about coronary heart disease: It's not about the cholesterol; it's about the atherosclerotic plaque that accumulates in arteries.

It's not cholesterol that grows, limits coronary blood flow, and causes angina. It's not cholesterol that "ruptures" its internal contents to the surface within the interior of the blood vessel and causes blood clot and heart attack. It's not cholesterol that fragments from the carotid arteries and showers debris to the brain, causing stroke. It's all plaque.

I took the same leap years ago, though not backed by hundreds of millions of dollars of marketing money. When I first called my book Track Your Plaque, some of the feedback I got from editors included comments like "I thought this was a book about teeth!" Even now, the word "plaque" in the book title and website is responsible for confusion.

But AstraZeneca is helping me clear up the confusion. As the word plaque gains hold in public consciousness, it will become increasingly clear that cholesterol reduction is not what we're after. We are looking for reduction of plaque.

If you are trying to develop an effective means to reduce or reverse coronary heart disease, then there are two simple equations to keep in mind:


Plaque = coronary heart disease

Cholesterol ? coronary heart disease


Plaque is the disease, cholesterol is not. Cholesterol is simply a crude risk for plaque.

While I'm no friend to the drug industry nor to AstraZeneca, some good will come of their efforts.

    I am currently in a battle with my "preventative" cardiologist.  she just handed me a bunch of Crestor due to a very high Lp(a) and family history of heart disease.  I have gone round and round with her about statins and she was willing to go the Niacin route first.  I was convinced that would work but something very strange occurred.  I don't mind the Niacin flush at all and I did take with food, aspirin, the whole 9 yards.  After being on the Niaspan for 12 days, I suddenly broke out into horrible hives all over my body and now 3 weeks later I still have some lingering rash/hives on my arms.  My diet and exercise program couldn't be better - I walk 6 miles a day, yoga 3 times a week, eat whole foods only, drink lots of water and I am just not sure what to do next.  My Lp(a) number is 135 and my total cholesterol is 267 with a not so good "ratio".  If anybody has any suggestions or comments I would love to hear them!

  • David

    3/21/2009 7:18:00 PM |

    Judy, make sure you take a close look at the hormones (estrogen, DHEA, thyroid, etc.), as these can influence Lp(a) to a pretty large degree.

    High dose EPA/DHA from fish oil is also really important. Consider up to ~6,000 mg EPA + DHA daily.

    Consume raw nuts and seeds. Almonds and ground flaxseed are great, and can help in dropping Lp(a).

    L-carnitine can help in lowering Lp(a), at least by a little bit.

    Not sure what you're including when you say your diet is made up of "whole foods." If this refers to things like "whole wheat," then that's problematic. Based on the research I've seen, those of us with Lp(a) (and yes, I am one of them too) are quite a bit more sensitive to the carbs. Eat carbs, and your Lp(a) goes up. Eat lower carbs, higher fat (particularly saturated), and your Lp(a) goes down. I would be loving on the coconut oil if I were you (and that's exactly what I do).

    As for exercise, I would start changing it up. That's an awful lot of walking, and it's not going to create the hormonal response that you need. The real benefit is in the high intensity stuff. Short, vigorous sprints, squats, that sort of thing. Check out www.crossfit.com for some idea of what I'm talking about.

    3/22/2009 3:30:00 PM |

    Judy,
    I second what David says above--it sounds like good, solid advice.
    I would add 3 things to the supplement category--Vitamin C (min 6000mgs/day) L-Lysine (min 6000mgs/day) and NAC, (min 1200mgs/day)
    The Vitamin C and L-Lysine combination is I'm sure you know, the Pauling-Rath formula--it's been around a long time, many swear by it, but it's never been clinically double-blind tested.  The NAC, I recently learned, is possibly the most powerful natural Lp(a) inhibitor out there, for now, anyway.  I was so swayed by what I read about it, I purchased a couple of bottles of it to add to Pauling-Rath, since I, too, am sometimes irked by the Niacin flushes I begin experiencing as I get closer to the 500mg dose--and this is after weeks of slowly titrating the dose so that I may avoid that uncomfortable event.
    Judy, also keep in mind, I've always read that 1)It's better for women to have higher cholesterol levels and 2) up until a few years ago, a cholesterol level of over 300 was considered high.  Now that '200' is the new '300', there seems to be quite a market for new prescriptions, nu?

    3/22/2009 7:49:00 PM |

    The Pauling/Rath therapy is indeed intriguing. Before I discovered Dr. Davis and the TYP program, I thought that the Pauling therapy was the answer to heart disease.

    I now believe and am convinced that there's more to it than that, and I think Dr. Davis has one of the best, most comprehensive programs for heart disease out there.

    However, this is not really a criticism, and I remain convinced that there is value to the Pauling/Rath therapy. It makes so much sense, at least theoretically in terms of reducing Lp(a), and it has quite a bit of anecdotal evidence behind it (not to mention the research carried out by Rath, complete with CT scans). It seems like the experience of doctors using this therapy with their patients varies quite a bit, though. Some doctors swear by it, while others say it just doesn't work. It's only for this reason that I usually don't bring it up until I've brought other ideas to the front that I know are very effective.

    I've got my dad on the Pauling therapy, along with these other things (basic TYP stuff), and we'll be getting his Lp(a) rechecked soon. Should be interesting to see how much it has come down, though I won't know which factor (niacin, diet, carnitine, fish oil, etc.) is creating the most change. I just decided to hit it with everything we've got.

    Oh, and it's the same with the NAC. There are pockets of stunning success, but there's also worry about long term safety and the development of pulmonary hypertension. Is that a real danger? I don't know. I would guess not, personally, but at the same time I'd rather mention the "tried and true" methods first that have the most overall benefit.

    I'm glad the Pauling therapy was brought up, here. I think it definitely should be looked into more, and people need to be aware of it as an option that many are having success with.

    This may be of interest to those who may want to reduce the risk of venous thromboembolism (VTE) with a statin (Crestor):

    http://www.usatoday.com/news/health/2009-03-29-statin-clots_N.htm

    Statin Crestor lowers risk of deep-vein clots

    "ORLANDO — (3/30/09) Researchers have shown for the first time that a potent cholesterol-lowering drug, Crestor, reduces the risk of deep vein thrombosis, or "economy-class syndrome," caused by potentially lethal blood clots that start in the veins and migrate to the lungs, sometimes after long flights.

    The evidence, out today, is the latest to emerge from the landmark JUPITER trial, which showed that statin treatments can cut in half the risk of heart attacks and strokes even in people with normal cholesterol levels."

    No other medicine has been shown to safely prevent these blood clots, which occur in at least 350,000 people a year and kill as many as 100,000 of them. The standard remedy once thrombosis has occurred is the drug warfarin, which, unlike statins, can promote bleeding.

    Statins are "a remarkably benign therapy," says senior investigator Paul Ridker of Brigham and Women's Hospital in Boston. "The thing that's really exciting is that there is no bleeding risk."

    Other studies have hinted that statins also reduce clot formation, but their power to prevent deep vein thrombosis was unknown. Ridker and his co-workers decided to use JUPITER to test the theory. A total of 17,802 people were randomly assigned to treatment and placebo groups. They were followed for nearly two years, on average.

    Deep vein thrombosis occurred in 34 patients taking Crestor and 60 people who were taking placebos, indicating that treatment reduced the risk of clots by 43%. Ridker says he believes that other statins would also reduce the risk.


    What I take from this;

    The dose of Crestor in JUPITER was 20mg.  Paul Ridker said that this is a remarkably benign therapy?  I think not, given Dr. Davis' descriptions of intolerable side effects that will inevitably occur to the majority of people at this dosage.  I've never used Crestor, but I have used 10mg Zocor and developed mild myopathy in my legs after only three weeks, so I'll take his word that I would be a poor candidate.

    I think the most interesting part of the press release is that JUPITER (like the other statin trials) in no way confirms what mechanism may be behind the reduced risk of VTE.  Could it be due to a lowering of vascular inflammation as indicated by a lower CRP?  That certainly makes sense.  It would be really great to get a definitive answer, since CRP can be effectively managed by other means than taking such a strong statin like Crestor.

Call me when you're having chest pain

Call me when you're having chest pain


I met a patient, Anna, yesterday. She was quite frustrated and frightened.

At age 50, Anna suffered a heart attack and received a stent to her left anterior descending coronary artery. What she found upsetting is that, because several members of her family had suffered heart attacks in their 40s (Dad--heart attack at age 45, paternal uncle--heart attack age 40, and even another uncle with heart attack in his late 20s), she had repeatedly asked her doctor whether she was okay.

She received the usual array of false assurances: "You're feeling fine, right? Then don't worry about it." "Look. Your cholesterol is in the normal range. Even your cholesterol/HDL ratio is fine." "Women don't get heart disease until later in life."

All proved absolutely false. As we talked, Anna exclaimed, "I think what I've been told all along is that we'll take you seriously when you finally have a heart attack!"

She's exactly right. The vast majority of times, heart disease is discovered by accident, usually because of an "event" like heart attack. This is like changing the oil in your car when it finally breaks down--it's too late.

CT heart scan, followed by lipoprotein testing and associated values, then correction of your specific causes. It's that simple.
